As a teenager I never saw the point of lights on my push bike, I could cycle around without hitting anything, so what was the point?
When I started driving a car however I realised how stupid and naive I was to believe that I didn't need lights on my push bike and then realised the lights aren't for the cyclist, they're for other motorists on the roads to see you, not for you to see.
I've just started cycling again and have some decent Cateye lights which cost about £60 and I wouldn't dream of cycling without them in the dark.
/doffs hat.
I have the same attitude towards my car's lights when the light's not particularly brilliant.
I'd rather be seen as early as possible to prevent some nob overtaking because they didn't see me coming the other way.
People who have no lights on or only sidelights in Fog are just retarded.
